Companies offer a full range of services, including unblocking, repairing, and replacing sewer lines or pipe, but some specialize only in certain areas. There are three main types of repair services:
All repairs performed in the city right-of-way must be done by a contractor licensed and bonded to work in Seattle. Visit Registered Side Sewer Contractors for more details.
Make sure you have all questions answered in legible writing at the time of service with the provider’s signature and date.
If your line is rootered, have the service provider write down the specific footage where the blockage was found (or where they think it is). Also have the provider mark the spot on the ground. This information is helpful in determining if the problem is within the city’s area of responsibility. The mark can be helpful if you must dig up the pipe to repair it.
Have the service provider write down the probable cause of the blockage. Knowing the type of blockage will help determine what method should be used to open it, and if regular maintenance of your side sewer is needed to prevent future backups.
TV cameras generally are not effective in determining what is blocking a line. They cannot see under water, so if a line is blocked and not draining, the camera won’t be able to see inside your pipes. Camera inspections are most useful after the blockage has been cleared to determine the condition of your pipes and where future problems might turn up.
